I have a 24r and have had a motor fail on the road. The video is accurate ,especially the part about needing a square drive bit to remove the motor retention bolt under the outside weather stripping. It is much easier to simply lift the motor on the inside of the camper. There is enough clearance for lifting the motor and dropping in a new one. If the slide is stuck too far extended then remove your trim molding and fix later. The molding is only nailed with nail gun brads. The motor replacement is very simple. Once in, retime the controller by either holding the slide button fully extended or retracted for an extra 2-3 seconds after full stop.
Regarding our repair. I had always worried about a slide motor failure on one of our month long outbound trips. All four slide motors are the same in the 24r. 1:300 lippert ( the 1:500 is for the side slide units). The motors are usually under $150 on Amazon and easy to acquire. The forward motor the side slide failed us due to water intrusion driving in rain, we did drive thru the tail end of Hurricane Irma with 30-40 mph rainy gusts a few years back. It failed on a subsequent trip. The smaller slides on the 24r are easy to push with the motor lifted. The repair took 15 minutes if you already have a spare motor and a square drive bit. Pike up a spare motor a consider yourself prepared.
